-WARPlNG-:MACHINE.

SPECIFICATION forming part of Letters Patent NO. 687,359, dated November26, 1901.

Application filed March 30,1901.

To all whom it may concern.-

Be it known that I, JOSEPH B. WHITNEY, a citizen of the United States,residing in Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Warping-Machines; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters and figures of referencemarked thereon, which form a part of this specification. 7

This invention relates to the operation of warping; and it has referenceparticularly to that portion of the mechanism usually employed forcarrying on this operation, which comprises a creel, thecondensing-reed, and the other accessories intermediate these parts.

The objects of the invention are, first, to so construct and arrange theseveral reeds of the mechanism that the threads will be subjected toonly the minimum of turns from the time they leave the spools on thecreel until they are about to be wound on the reel and that such turnsas they have to make will be around smooth rounded parts, so that theabrasion of the threads will be as much as possible avoided; secondly,to provide for such an arrangement of the threads on the creel thatthereby the number of spools may, without inconvenience otherwise, beincreased and the capacity of said creel thus augmented; thirdly, toprovide a simpler and more readily-operated form of adjustablecondensingreed than is at present in use; fourthly, to provide means forimparting such a disposition to the threads as they pass through thecondensing-reed that the strain which is exerted by the outermostthreads on the dents of the condensing-reed as an incident to therelatively sharp turn which they make at this point will be properlydistributed, and, lastly, to provide an improved form of mounting forsaid bars.

The invention will be found fully illustrated in the accompanyingdrawings, wherein corresponding letters and figures of referenceindicate like parts, and wherein- Figure 1 is a top plan view of thatportion Se ial N 53.589. (No model.)

of a warping mechanism in which my invention resides. Fig. 2 is acentral longitudinal sectional view of the mechanism as illustrated inFig. 1. Fig. 3 is a horizontal sectional view through the reeds on thecreel, showing the arrangement of the threads as they pass olfsaidcreel. Fig. 4 is a detail view illustrating a slight modification of theinvention. Fig. 5 is an enlarged top plan viewillustrating theadjustable condensing-reed. Fig. 6 is a sectional view of the frontportion of said reed. Fig. 7 is a sectional View of one of the reedmembers, and Fig. 8 is aview in front elevation of the cross-reed frameand theelevatory bar which coacts with the cross-reed to effect theseparation of the threads into two sheds.

The reference character a in said drawings designates the creel, uponwhich is arranged in the usual manner a series of spools b. On the topof this creel are mounted a reed c and two horizontal bars (Z,preferably of glass and preferably arranged the one directly above theother. These bars may be either secured directly to the reed orseparately mounted, as desired. A short distance in front of the reed cis arranged another reed e and also another horizontal barf. The saidreed and bar may be supported on the creel by brackets g, or, ifdesired, they may be carried on a separate stand h, designed for thepurpose. The reed e has twice as many dents 7;, and consequently twiceas many spaces, as the reed c. The threads areled up from the spools inpairs, of which one thread passes over the lower bar (1 and the otherthread over the upper bar at, and thence together through the same spacebetween the dents 't'. After leaving the reed c the threads in each pairare separated again, each thread passing through its individual dent inthe reed e. By passing the threads through the reed c in two sets, inwhich the threads of one are directly above the corresponding ones inthe other, the width of the body of threads is reduced just onehalf, andthus the number of spools on the creel may be materially increased. Thisarran gement of the threads is not allowed, moreover, to interfere withthe single-plane disposition thereof, which is found desirable afterthey leave the creel, for thebar f adjoining the reed e acts to bringthem into the said disposition.

j designates a suitable support which is arranged, as usual, at adistance from the creel a. On this support is mounted a skeleton frameIt, having brackets Z m n and uprights 0. At the end of said frame whichis adjacent the creel is mounted the cross-reed p. In guides q, securedto the front face of this reed, work the ends of a horizontal elevatorybar r, preferably of glass, which has a down- Wardly-extendingprojection s, penetrating a lug t, which extends from the reed-frame,the said projection and lug constituting an auxiliary guide for the bar.Pins'u are mounted in the guides q, said pins being adapted to sustainthe bar in its elevatory position and being removable, so that the barmay be lowered. In the brackets Z is mounted a horizontal cross-bar '2).In the brackets m is mounted another and elevatory cross-bar w, the samehaving arms 00, which are fulcrumed in said brackets. In the brackets nis journaled a revoluble cross-bar y, which is the part which thethreads last engage before passing onto the reel.

z denotes a block, which is mounted upon a central rib 1 of the framelo. Back of this block is arranged a transverse cross-piece 2. On saidblock and cross-piece is supported the condensing-reed 3. The block isslightly higher than the cross-piece, and their top faces are inclinedparallel with the normal plane of the sheds, so as to bringthecondensing-reed into proper disposition with regard to said threads.The said reed 3 is in two sections 4, which are secured together at oneend by hinges 5 and the frames of each of which may be reinforced bybrass strips 5'. The pivot 6 for one of the hinges is in the form of abolt 7, which extends down through the block z and through the rib 1,having a wing-nut 8 whereby the cross-reed is secured in place.reed-sections 4 are hinged, as at 9, to the free ends ofpivotally-connected links 1.0. The pivotal connection between the linksis in the form of a bolt 11, having a wing-nut 12, the said boltpenetrating a slot 13 in the frame 7c and, with its wing-nut, affordingmeans for adjusting the reed -sections in an obvious manner.

In the uprights 0 are mounted the parting bars 14. The ends of thesebars are tapered, as at 15, and are adapted to fit intocorrespondingly-shaped recesses 16, which, as best seen in Fig. 2, arecurved and turned away from each other at their lower ends. By thearrangementjust described when the parting-bars are in positionmaintaining a cross in the threads the latter in tending to force themaway from each other will keep them from being accidentally thrown outof place. It should be remarked that these partingbars are of a diameterwhich approximates the length of the dents in the condensing- The rearends of the reed and that the one which is next to the reed is close tothe same. Ordinarily, and especially where a considerable number ofthreads are led through each dent in the condensing-reed, there is agreat strain upon the outermost dents of the reed. This is due to thefact that these threads have to make quite a sharp turn at practicallythe middle portions of the dents when they reach the reed, and if thedents of the reed are of delicate material, as they often must be inorder to accommodate a great number of threads in a small space, theyare often damaged. By therefore making the parting-bars of a diameterwhich approximates the lengths of the dents of the condensing-reed andbringing the adjacent one close to the reed the objec-- tion referred tois overcome, for the strain of the outermost threads is now imparted tothe dents near the ends thereof instead of near their middle portions.

In order that the threads may pass from the creel to the condensing-reedwithout being subjected to any undue abrasion, I preferably constructsaid creel and also the reeds c, e, and p in arc-shaped form inelevation, so that the threads will have. practically no contact Withthe dents at any point. With a further view to the same object I providethe reeds of the mechanism throughout, with the excep tion of thecross-reed, with round glass dents. The above-mentioned object ofavoiding the concentration of the strain of the outermost threadsagainst relatively small portions of the surfaces of the engaged dentsof the condensing-reed may be also attained by the arcshaped bar r,which being horizontal, while the threads are not so, presents to thelatter a curved surface, with the consequence that each of the'outermostthreads stands a little higher than its next inner neighbor. Thetendency, therefore, is not only to dispose the threads in a verticallayer one after another against the engaged dent of the reed, (it beingremembered that a considerable number of threads are often extendedthrough each space of a condensing-reed,) so as to avoid theconcentration of their strain on a small portion of the dent, but toalso arrange the threads in their natural order and so avoid theirbunching and the consequent breaking of some of them. It will beunderstood that any other means which tends to successively elevate thethreads will also subserve the same function; that, moreover, the nearersaid curved bar or other similar part is placed to the cross-reed andthe greater the angle between its plane and that of the warp the moreemphasized will be the desired arrangement of the threads. The bar 0should, under the circumstances now being referred to, be removed out ofcontact with the threads, else it will counteract the efiect aimed at.If the bars d areso arranged on the creel that they are disposed betweenthe planes in which are the tops and bottoms of the spools-that is toIIO say, the heads thereofthe threads will not project out free wherethey might possibly be caught and broken.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination of a creel, a reed ar ranged substantially above saidcreel, and bars disposed in substantially superposed dispositionadjacent said reed, a plurality of threads being adapted to be extendedthrough each space in the reed and individually over the bars,substantially as described.

2. The combination of a creel, a reed arranged substantially above saidcreel, bars disposed in substantially superposed disposition adjacentsaid reed, a plurality of threads being adapted to be extended througheach space in the reed and individually over the bars, and another baradapted to engage all said threads to effect a single-plane dispositionthereof, substantially as described.

3. The combination of a creel, a reed arranged substantially above saidcreel, and bars disposed in substantially superposed dispositionadjacent said reed, a plurality of threads being adapted to be extendedthrough each space in the reed and individually over the bars, and saidbars being arranged in a plane between those of the ends of the spoolson said creel, substantially as described.

4. The combination, with the creel and the condensing-reed, of reedsinterposed substantially between the spools on said creel and saidcondensing-reed, each pair of dents in each reed being disposedsubstantially at right angles to the direction in which theircorresponding thread extends, substantially as described.

5. The combination, with a suitable support having a slot, of a pair ofreed-sections pivotally connected at one end and carried by saidsupport, links pivotally connecting the other ends of saidreed-sections, and a bolt adj ustably securing said links together andto the support, said bolt penetrating said slot, substantially asdescribed.

6. In a mechanism for maintaining series of threads in crosseddisposition, the combination, with a suitable support, of a pair ofuprights mounted on said support and having downwardly-extendingrecesses turned away from each other at their lower ends, andparting-bars seated in said recesses, and adapted to maintain betweenthem the crossing in the threads, substantially as described.

7. In a warping-machine, the combination, with a suitable support, of apair of uprights mounted on said support and having downwardly-extendingrecesses turned away from each other at their lower ends, parting-barsseated in said recesses and adapted to maintain between them a crossingin the threads, and a reed also mounted on said support and disposedappreciably adjacent one of said parting-bars, said parting-bar having adiameter approximating the length of the dents in said reed,substantially as described.

8. The combination, with means for maintaining the threads of the warpin substantially side-by-side disposition in one portion of said warp,of a condensing-reed disposed remote from said means and adapted toreceive several threads in each of its spaces, and a device formaintaining the threads in each reed-space in superposed disposition,said device being disposed between said means and the reed and having acurved face engaging the threads, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this22d day of March, 1901.
